BED-SPRING- FABRIC.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filed August 31, 1917. Serial No. 184,300.

To all whom it may concern:

Be it known that I, GARY B. SMITH, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a new and useful Bed-Sprin Fabric, of which the following is a speci cation.

The present invention relates to bed-spring fabric, and is particularly an improvement over the cross-tie chain fabric for bed springs disclosed in my Patent No. 1,247,024, granted November 20, 1917.

One of the objects of the invention is the provision of cross-tie chains with the links of which those chains, similar to the ones shown in said patent, are assembled, providing an all-chain fabric instead of using twisted wire. In other words, the present construction utilizes chains for the strands or elements comprising twisted wire in said patent.

The invention resides in the novel assemblage of the sets of chainswhich cross one another, whereby to provide a thoroughly substantial fabric, having the advantages of the fabric disclosed in said patent, and in addition utilizing cross-tie links.

With the foregoing and other objects in View, which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of'construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention can be made within the scope of what is claimed without departing from the spirit of the invention.

The invention is illustrated in theaccom panying drawings, wherein:

Figure 1 is a fragmental plan view of one Style of fabric constructed in accordance with the present invention. 7

Figs. 2 and v3 are sectional views thereof on the respective line 2- 2 and 33 of Fig. 1, parts appearing in elevation.

Fig. 4 is a fragmental plan view of a modified form of'fabric;

Figs. 5 and 6 are sectional views on the respective lines 55 and 66 of Fig. 4, parts a pearing in elevation. I

Fig. $18 a detail view of a modlfied form of link.

Referring to Figs. 1, 2 and 3, the fabric shown therein comprises longitudinal and transverse chains or fabric-elements crossing'one another approximately at right angles. The longitudinal chains (called other set and second-named set in the claims) are composed of the doubled wire or U- shaped links 1 having the loops 2 and hooks 3 at opposite ends with the loops 2 bent at an obtuse angle to slidably engage the companion links and move against the hooks 3 by a cam action, for locking said hooks closed, as covered in said patent. The trans verse chains (called, one set and first-named set in the claims) also comprise doubled wire links 4 having straight parts disposed side by side and having the loops or eyes 5 and hooks 6 at'opposite ends, said hooks embracing the loops. As shown, the hooks of both sets of chains are disposed downwardly, so that the upper surface of the fabric is comparatively flat and devoid of terminals of the wire, soas not to injure the mattress. In assembling the two sets of chains, the hooks 3 embrace the links 4 at their hooked ends, and the hooks 3 extend through the hooks 6, thus interlocking the two sets of chains together, to hold the longitudinal chains spaced apart. The transverse chains are disposed underneath the longitudinal chains, with the links 1 bearing on the links 4, and the hooks 3 engaging under the links 4 and over the hooks 6 within the lastmentioned hooks. Thus, the hooks 3 are closed on the links 4, and the hooks 6 are closed on the hooks 3, with the loops 5 abutting the hooks 3, and providing a pivotal connection between the links 4 so that the fabric will be flexible. The links 1 are also pivotally and slidably connected, and the loops 2 thereof in moving under and binding against the hooks 3, will lock the links 1 together so that they cannot be pulled apart. The greater the strain on the longitudinal chains, the greater will be the tendency for the loops 2 to hold the hooks 3 closed.

Another feature of the invention resides in the fact that the coiled wire tension springs or individual independent members 7 atone end of the fabric have their hooks or loops 8 seated over the links 4 at said end of the fabric and engaging under the corresponding hooks 3, whereby to hold said hooks closed, and prevent the fabric from tearing loose from the springs 7. The springs thus not onl serve to yieldably support the correspon mg end of the fabric,

but also hold the hooks 3 at that end closed upon the transverse chain, providing a strong and serviceable construction.

The coiled wire tension springs 9 at the other end simply have their hooks. 1O engaged with the loops 2 of the links 1 at that end, so that said links cannot tear loose from the springs.

The modification shown in Figs. 4, 5 and 6 is similar to the above, withthe exception of the cross chains. In this case, said cross chains comprise doubled wire links 4, having the loops or eyes 5 and hooks 6 at their opposite ends, and provided between their ends and near the loops 5 with supplementary loops or eyes 5", the hooks 6' engaging the loops 5. The links 1 rest upon those portions of the links 4 between the loops 5 and 5", the hooks 3 engaging the links 4: between the loops 5 and 5", and the loops 2 in extending between said loops of the links 4 will hold the links 1 spaced apart properly.

Instead of making the links 1 of tapered form, the side portions thereof can be brought together, as seen at 11 in Fig. 7, and the loops 2 closed, so as to avoid any possibility of tangling when the loops 2 slide on the companion links.

Having thus described the invention, What is claimed as new is:

1. A fabric embodying two sets of chains crossing one another and each comprising doubled wire links each having a loop at one end and hooks at the other end, the hooks of the links of one set engaging the loops of their companion links to connect them, the hooks and loops of the links of the other set embracing and crossing, respectively, the doubled portions of the links of the first-named set, with said loops surrounding and slidably contacting with said hooks to hold them closed on the links of the first-named set when the links are under strain and to connect the links of the secondnamed set.

2. A fabric embodying two sets of chains crossing one another and each comprising doubled wire links each having a loop at one end and hooks at the other end, the hooks of the links of one set engaging the loops of their companion links to connect them, the links of said set having portions disposed side by side in contact, the hooks and loops of the links of the other set embracing and crossing, respectively,said portions with the loops surrounding and contacting slid'ably with said hooks to hold them closed on said portions and to connect the links of the second-named set.

3. A fabric according to claim 2, with those portions that are disposed side by side provided with separated portions between which the second-named hooks and loops are disposed. V

4. A fabric including a transverse fabric element, longitudinal fabric elements .extending therefrom and each having at one end a hook embracing the transverse fabric element, and individual independent Inembers, separable from said fabric elements, to take up the strain from boththe longitudinal and transverse fabric elements, disposed beyond the ends of the longitudinal fabric elements and having hooks extending across the transverse fabric element and around the aforesaid hooks to hold them closed on the transverse fabric element and to detachably connect the ends of the longitudinal fabric elements and said members, the transverse fabric element having por tionsholding the hooks in spaced position thereon.

5. A fabric including longitudinal and transverse sets of Wire link chains crossing one another and connected together, the longitudinal chains each having at one end a link with a hook embracing a link of one endmost transverse chain, and individual independent members; separable from the chains and to take up the strain therefrom, disposed beyond the ends of the longitudinal chains and having hooks extending across said transverse chain and around the aforesaid hooks to hold them closed on the links of said transverse chain and to connect the ends of the longitudinal chains and said members. 7

6. A fabric according to claim 5, with the links of the transverse chain that are embraced by the hooks of the longitudinal chains provided with portions holding the hooks in position thereon.

In testimony that I claim the foregoing as my own, I have hereto afiixed my signature in the presence of two witnesses.
